Purpose: XtreemFS is a fault-tolerant distributed file system for general-purpose storage.
Replication: It replicates files across storage servers and can automatically fail over to a backup replica if the primary fails.
Read-only replicas: It supports full and partial read-only replicas for immutable files, which can be used to build a cache across datacenters.
Scalability: The site says an installation can scale to thousands of storage and metadata servers by adding or removing storage servers.
Compatibility: XtreemFS offers POSIX compatibility and can be used as a drop-in replacement for NFS.
Security: It has built-in SSL and X.509 certificate support, and the site says it can run over the internet without a VPN.
Hadoop: A Hadoop client is available for using XtreemFS as an HDFS replacement.
Deployment: The project provides Linux distribution packages and precompiled client packages for Windows and Mac OS X.
Use cases: The site lists filer replacement, HPC and Hadoop clusters, VM block storage, and cross-branch data sharing as use cases.
Support: Users can ask questions on the public mailing list and report bugs through the GitHub bug tracker.
Limit: The FAQ says a single volume may contain up to tens of millions of files; it reports no known limits for the number of volumes and services.
